Motor / Actuator Drivers for DC Brush Motor Series

Automotive 6ch Half Bridge Driver

with SPI Control

BD16939AEFV-C

General Description

Key Specifications

The BD16939AEFV-C is 6ch half bridge driver for

automotive applications. It can drive compact DC

brush motors directly and each output can be

controlled in three modes (High, Low and High

Impedance).

MCU can control the driver via 16bit Serial

Peripheral Interface (SPI). The absolute voltage

is 40V rated with low ON resistance

packaged in compact package, which contributes

to realize high reliability, low energy consumption

and low cost.
